"I'm sorry, Anvar, I shouldn't tease. What's their name, this person?" "Kasivelieth Sey-Dariyavis. She's from Kasith-Varouin." He finishes tying the cloak and looks up. "Mother, when did Uncle Invar change his name?" "He started using "sey" when he entered the Great Library." "Did he ever say why?" "I never asked him. But it was common practice among scholars. A way to avoid awkward questions." "Really? That's all?" He can't help sounding cheerful. "There are as many reasons to use that particle as there are people, Anvar," his mother says. "Don't assume, just be polite." "Yes, mother," and it is his turn to tease.
